Subject [jira] Updated: (HARMONY-6248) Wildcard subjectAltName dNSName entries throw IOException

Tim Ellison updated HARMONY-6248:
---------------------------------

    Attachment: harmony-6248.patch

Ian,

I assume that the wildcard value only makes sense at the left hand side, and we would not
allow a simple '*' as the full dns, i.e. it should only be allowed as a "*." name prefix?

Please try this patch and see if it fixes the issue for you.

> Using the DRLCertFactory JCE provider, calling getSubjectAlternativeNames() on an X509Certificate
throws IOException if the subjectAltName extension in the certificate contains a dNSName entry
with a wildcard (such as "*.example.com").
> This is ultimately because GeneralName::checkDNS() does not allow wildcard entries. 
RFC3280 and RFC1034 both discuss wildcards, although a strict reading of RFC3280 would *appear*
not to allow for them in a subjectAltName dNSName.  However, RFC3280 explicitly allows for
application-specific semantics of use of wildcards in subjectAltName.  As the Harmony code
currently stands, it is not possible for an application to even retrieve the subjectAltName
values if they contain a dNSName that does not strictly conform to the "preferred name syntax"
in RFC1034.  So it is not possible for an application to make the decision on what semantics
to apply to a wildcard value.
